What is the most important information I should know about olanzapine (Zyprexa, Zyprexa Zydis)?

Olanzapine is not for use in psychotic conditions related to dementia. Olanzapine may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions.

You may gain weight or have high cholesterol and triglycerides (types of fat) while taking this medicine, especially if you are a teenager. Your blood may need to be tested often. Visit your doctor regularly.

Olanzapine can cause high blood sugar (hyperglycemia). If you are diabetic, check your blood sugar levels on a regular basis while you are taking olanzapine.

Olanzapine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Avoid drinking alcohol while taking olanzapine.

Avoid becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking olanzapine.
